چکیده
Abstract The treatment of stone surfaces for their protection from ageing caused by natural and anthropogenic effects is an open issue in materials development Cultural Heritage. We thought interesting to verify the suitability a modified cellulose biofilm filled with halloysite nanotubes as wax compatibilizers design protecting layer. A hydraulic mortar was selected prototype. To improve physico-chemical properties covering layer, microparticles have been incorporated control transport, consolidation wettability features. In particular, different application protocols studied, namely brushing spraying, assess whether proposed procedures can be scaled up. Colorimetric analysis has carried out evidence applicability terms color alteration after treatment. Water adhesion investigated measuring contact angle values function time obtain information on spreading adsorption phenomena. These correlated microstructure evidenced both electron optical microscopies. Graphic abstract

Surface Improvement of Halloysite Nanotubes
A novel development on halloysite-polyvinyl alcohol (HNTs-PVA) nanocomposites has been conducted using malonic acid (MA) by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (...

A sandwich-like antibacterial reagent (Ag/HNTs/rGO) was constructed through the direct growth of silver nanoparticles on the surface graphene-based HNTs nanosheets. Herein, various nanomaterials were combined by adhesion effect of DOPA after self-polymerization. Ag/HNTs/rGO possess enhanced antibacterial ability against E. coli and S. aureus compared with individual silver nanoparticles, rGO na...
متن کاملFlexural Properties of Halloysite Nanotubes-Polyester Nanocomposites Exposed to Aggressive Environment
This study aimed to investigate the effect of aggressive environment on the flexural properties of halloysite nanotubes-polyester nanocomposites. Results showed that the addition of halloysite nanotubes into polyester matrix was found to improve flexural properties of the nanocomposites in dry condition and after water-methanol exposure. Significant increase in surface roughness was also observ...
